Latex使用：在latex中添加算法模块

在Miktex下有三个latex algorithm包，分别为：algorithm，algorithmic，algorithm2e三个，其中algorithm，algorithmic经常成套使用：

latex中algorithm模板为：

latex文件中顶端加入的package：

usepackage{algorithm}
usepackage{algorithmic}
usepackage{setspace}

算法块代码：

egin{algorithm}[htb]
setstretch{1.35} %设置具有指定弹力的橡皮长度（原行宽的1.35倍）
caption{}
label{alg:Framwork}
egin{algorithmic}
REQUIRE ~~\
The set of positive samples for current batch, $P_n$;\
The set of unlabelled samples for current batch, $U_n$;\
Ensemble of classifiers on former batches, $E_{n-1}$;


ENSURE ~~\
Ensemble of classifiers on the current batch, $E_n$;
Extracting the set of reliable negative and/or positive samples $T_n$ from $U_n$ with help of $P_n$;\
label{ code:fram:extract }

Training ensemble of classifiers $E$ on $T_n cup P_n$, with help of data in former batches;\
label{code:fram:trainbase}

$E_n=E_{n-1}cup E$;\
label{code:fram:add}

Classifying samples in $U_n-T_n$ by $E_n$;\
label{code:fram:classify}

Deleting some weak classifiers in $E_n$ so as to keep the capacity of $E_n$;\
label{code:fram:select}

$E_n$;\
end{algorithmic}
end{algorithm}

实际算法结果图示为：

第二种用法：

使用algorithm2e包进行处理

documentclass{article}
usepackage{algorithm2e,setspace}

egin{document}

egin{algorithm}
setstretch{1.35}
SetAlgoLined
KwData{this text}
KwResult{how to write algorithm with LaTeX2e }
initialization;
While{not at end of this document}{
read current;
eIf{understand}{
go to next section;
current section becomes this one;
}{
go back to the beginning of current section;
}
}
caption{How to write algorithms}
end{algorithm}

igskip

egin{algorithm}
SetAlgoLined
KwData{this text}
KwResult{how to write algorithm with LaTeX2e }
initialization;
While{not at end of this document}{
read current;
eIf{understand}{
go to next section;
current section becomes this one;
}{
go back to the beginning of current section;
}
}
caption{How to write algorithms}
end{algorithm}

end{document} 

上述代码分别对应两个算法，所获得的算法块分别为：

Latex中的常用算法块如上所述，使用过程中其它技巧可查询之后进行设置。

上述记录仅用来对latex使用过程中的心得体会进行总结。

个人感悟：写latex一定要静下心，要不然很容易出现低级错误。遇到不会的格式或方法，勤用搜索引擎去寻找答案。

其实在这里自己是被行距问题卡了很长时间，遇到的问题是因为算法的行距太小：

行距问题的设置网络搜索就可以解决，查阅刘海洋的《latex入门》也可以得到很好解决。
